ABSTRACT:
The invention shows a hip joint socket and its manufacture, with the hip joint socket including a thin walled metallic outer shell with anchoring pins which is firmly connected to an inner shell of plastic. Since the bearing surface of the inner shell is not produced until after the assembly, a high accuracy of shape of the bearing surface results together with a relatively elastic outer shell and with good anchoring aids for a primary anchoring.
